Application December 5, 1938, Serial No. 243,932 12 Claims. (Cl. 189-72)This invention relates to windows of the sliding or double hung type.One of the objects of the invention is to provide a frame and sashconstruction in which the frame has a pair of guide rails for each sash,the sashes being provided with resilient sliding contact members adaptedto slide upon the guide rails and to seal lthe windows against leakageand prevent rattling. The resilient engagement'is such that while thewindows are at all times maintained tight against the weather, thesashes slide freely, so that Athere is no chance of sticking or binding.Other objects of the invention are to provide an improved constructionfor permitting removal ofy the sashes, improved means for permittingaccess to the counterbalance pockets, improved means for securing theframes in the window openings of the building, and an improvedconstruction whereby jamb members of adjacent window umts may be securedtogether to iorm multiple units A back of the channel.

provided with reinforced mullions. Other -objects and advantages willappear from the fol` lowing description of certain embodiments of theinvention chosen to illustrate the principles thereof.

In the accompanying drawings:

Figure 5 is a horizontal section of a vmodiiied Vconstruction of window;

Figure 6 is a perspective view showing a portion of the jamb member ofFig. 5 illustrating a form of bonding loop for interlocking with themasonry Wall;

Figure 7 is a vertical section of another modi-- 2l, the lips 2l on theopposite flanges being directed towards one another. The lips 21 enclosepockets for receiving counterbalancing means,

such for instance as the drum type spring counterbalances indicated lat28. When the jamb member is to be mounted directly in a masonry wall, asshown, for example, in Figure 3, bonding means are attached to the backof the channel, so as to project into the masonary. Such a bonding meansis shown at 30, and comprises a corrugated strip of metal embedded inthe masonry and having a flange 3| at its end adapted to be attached tothe back of the channel in any suitable manner, as for instance by beinginserted behind a tongue 32 bent out from the When two adjacent windowunits are to be mounted together, as shown in Fig. 1, then the two jambchannels are placed back to back, as shown in Figure 4, and are securedtogether by means of cover channels 35 which lt over the adjacent flangeportions of the jamb channels and may be secured in position in anysuitable manner, as by means of screws or'rivets 36. In this way a Verysolid mullion is secured and a smooth finish is provided between the twowindow units. If the window is high and extra strength is desired, areinforcing bar 31 may be enclosed in the space formed by theoff-sets-in the backs of the two jamb channels. e

The header member 2| shown in Fig. 2 is of metal, rolled or.otherwisesuitably shaped to form, and is preferably provided with a turnedoverbead 40 at its inner edge, with a central downwardly projecting rib 4|,with a narrow fold or rib 42 and with an outer folded-over portion 43which protects the outer margin of the sash from the weather and servesas a means for carrying a resilient sealing member 44 for engagementwith the top rail of the upper sash. For the purpose of holding thesealing member 44, the horizontal fold of the portion 43 terminates in alip 45 which engages the outer bend of the sealing member. The header isalso provided with a rib 46 against which the back of the sealing memberrests. The rib 42 .constitutes a guard and limiting device for the freeedge of the sealing member which engages the bead when the sash .ismoved down, and serves to retain'the sealing member under initialtension. The edge of the bead 42 also forms a stop to limit the upwardmovement of the sash.` An angle iron 50 (or series of angle brackets) ispreferably secured at its lower end in the inside of the rib 4I, itsprojecting flange being secured in the masonry or attached to a lintel5l, in any suitable manner as by means of screws 52.

The'sill 22 comprises a member formed into two steps and 6| and havingan inclined por-A tion 62 forming an apron which terminates at its outeredge in a. downwardly turned flange 63. 'I'he sill is completed by apair of angle plates 64 and 65 secured to the upper step 60 and to theflange 63, respectively. If desired, the sill may be filled with cementfor reinforcing purposes. The overhanging portion of the flange 63 formsa pocket 66 for caulking.

For guiding the sliding sashes the jamb members are provided with spacedguide ribs which are preferably united into a single unit by a web 1|.The web 1I is secured to the inner face of the off-set portion 25 of themain jamb channel member and the extremities of the outer legs 13 of thesash guide ribs 10 preferably embrace and flt against the ends of theoff-set 25. The webs 1| are removably secured by any suitable means,such as screw 16. The guide members 10 and web 1| are preferably formedin two halves divided along a horizontal line near the middle of thewindow as indicated at 11 in Fig. 2, so that either half may be removed,thereby permitting the sash to be removed.

The sashes comprise topfbottom and meeting rails which may be of anysuitable construction and provided, where necessary, with sealingstrips. The side rails of the sashes are channel shaped and carryresilient sealing and guidingmembers adapted to slide upon the guideribs 10. As shown in Figs. 3. and 4, the sashes are shown as madeofextruded metal and comprise an undercut putty seat 80,. a glasssupporting flange 8|, a front flange 82 towards the outside of thewindow terminating in an overhanging lip 83 and rear fiange84 towardsthe inside of the Window, terminating in an overhanging lip 85. There isa groove 86 in the bottom ofl the sash channel adjacent to the flange84. The resilient sealing and guiding member comprises a strip of bentresilient sheet metal or other suitable material which has a baseportion 90 seated in the groove 86 andl a flange 9| seated against theinside of the flange 84. The flange 9| terminates in a reversely bentresilient tongue 92 preferably having a raw or unreinforced edge whichis received behind and protected by the shoulder 93 formed at the edgeof the base 90 adjacent to the wall of the channel 86 towards theoutside of the window. The unreinforced edge of the tongue 92 islongitudinally flexible so that it will conform to any irregularities ofthe rib and form a tight seal therewith at all times. Springing 'fromvthe shoulder 93 of the base 90 of the resilient strip is a secondresilient,

flexible edged tongue 95 which is adapted to engage the inner edge ofthe guide rib 10. The resilient tongue 92 engages the inner side wall ofthe guide rib and serves to hold the sash in such position that the edgeof the lip 83 bears against the outer surface of the guide rib. A threeline engagement is thussecured between the sash and the guide rib, oneline of engagement, namely, that of the edge of the lip 83 beingengagement of one rigid part against another, while the other two linesof engagement are with the resilient tongues 92 and 95.` While there arethus three -points of sealing against the weather, nevertheless alimited movementof sash, both in the plane of the glass and transverselythereto, is permitted, so that there can be no binding, and the sashwill slide easily at all times and under all conditions. The sealingstrips are preferably similarly placed in both upper and lower sashes sothat in each instance the engagement between the lip 83 of the sash ison the side of the guide rib towards the outside of the building. Thusthe wind pressure on both sashes is sustained by the contact of theserigid members. As the flexible sealing and guiding strip is contained inthe edge of the sash and moves therewith, it is never exposed to theelements or to tampering. with, as may occur where the resilient stripis mountedin the jamb and is always partly uncovered by the sash.

In the construction shown, each sash is provided with a bracket |00 forengaging with the counterbalancing means 28. End plates |0| and |02 (seeFig. l) are preferably removably secured to each end of each sash stilechannel by any suitable means such as screws, not shown. The weatherstrips are thus secured in place from accidental displacement andprotected from ingress of dirt and moisture'.

Referring to the construction in Figs. 5 and 6 the jamb here showncomprises a bent or rolled metal channel member ||0 having flanges II|preferably terminating in bent-over edges II2,

there being outwardly projecting ribs |I3 formed at each edge of thebase of the channel. Near the center, the bottom of the channel is bentinwardly to form a supporting leg I I4 adapted to carry the web I I5connecting a pair of sash guiding ribs IIS. The web |I5 is preferablyoff-set to fit over the edge of the leg |I4, and may be removablysecured thereto in any suitable manner as by screws I I8. The web andsash guiding member is preferably formed in two horizontal halves asdescribed in connection with the guide rib members shown in Figs. 1 to4. For reinforcing the jamb and assisting in securing it in the masonrywall, a flange plate or angle |20 may be used, its flanged end beingsecured in the bottom of the leg I I4. To interlock the jamb with themasonry, a bonding loop |22 may be employed, this loop being shown ascomprising a rod bent into loop form and corrugated and havinghooked'ends |23 which hook into slots |24 formed in the back of the jamb|I0. The hooked ends |23 are preferably bent at an obtuse angle to therods as shown so that by hooking them partly or wholly into the slots arange of adjustment between the jamb and the rods built into the masonryis obtainable.

The sashes are shown as formed of extruded metal shapes having means forreceiving and holding the glass, each stile having an outer flange |30terminating in a lip |3I adapted to bear against the outer wall of asash guiding rib |i6, and an inner straight flange |32. In the anglebetween the flange |32 and the base |40 are formed a pair of ribs |45and |46 which are adapted to engage and retain the bent portion |41 of aresilient sealing and guiding member which is provided with tworesilient tongues |48 and |49 adapted to engage' respectively with theside and inner edge of the sash guiding rib ||6. The pressure of thetongue |48 against the inner face of rib IIB serves to drawthe edge oflip I3I against the outer face of rib IIE so that a three point sealingengagement between the sash and guide rib isprovided. Two of the pointsof engagement are yielding, While the third is rigid metal to rigidmetal so that while the sash is tightly sealed against the weather, itis yfree to slide at all times without jamming or rattling.

Figures '7 and 8 show a modified construction ofwindow in which eachjambis formed of a channel |50 at each edge of which is a flange |5|terminating in a lip |52. The central part of the channel is off-set asindicated at |53 and the sashes are guided by two guide ribs |54connected by a web |55. The member comprising the ribs and web `isremovably secured in place in any suitable manner, as by screws |51, andis divided horizontally intwo parts as mentioned heretofore inconnectionr with the other forms of the invention. The removal of theguide rib members permits removal of the sashes and also provides accessto the counterbalancing means indicated at |58. The sash stiles areofchannel form and each comprises a base |60 carrying glass and puttyretaining means and inner and outer flanges |6| and |62 which have lips|63 at their edges and lugs |64 placed a short distance from the base|60. Sash sealing and guiding members of resilient material are mountedin the stiles and in the form shown comprise a curved base adapted tocontact with the inner end of a guide rib |54 and two inwardly bowedtongues |66 adapted to engage the sides of the guide rib. Relativelyacute bends connect the tongues with the curved base |65, these bendsinterlocking beneath the Iugs |64 and the edges of the tongues beingretainedbehind the lips |63. The sash guiding members are thus firmlyretained in the sash stiles. In this construction it is seen that thereare three points of sealing engagement between the sealing and guidingmembers and the sashlguide rib, namely the two contacts between thesides of the rib and the tongues and the one contact between the end ofthe rib and the center of base |65. All of these contacts are weathertight but yielding so that the sash floats freely and slides easilywithout binding or jamming. Y

The header of the window shown in Fig. 7 comprises a non-ferrous ornon-corrosive member |80 which is bent to provide a parting bead |8| andat its outer edge is formed into a flange |82 which terminates in areentrant lip |83. Near the ange |82 the member |80 is bent to form abead |84. A resilient metal sealing member is provided for engagementwith the top rail of the sash. This sealing member comprises a base |85having a hook-shaped flange |86 at one edge adapted to engage over thebead |80, the.

resilient member also having a flange |81 lying inside of the flange|82. Flange |81 is formed at its outer edge with a bend |88 adapted toengage under the reentrant lip |83 to assist in holding the sealingmember in its recess. The edge portion of the sealing member beyond thebend |88 is bent upwardly to form a resilient tongue |89 which bearsagainst the outer face lof the top rail of the sash so as to seal thejoint at that point. The top rail of the sash also bears against theportion 86 over the bead |84 and the inner face of the sash is held inclose engagement with the face of the parting strip |8| by reason of thepressure of the tonguev |89. A

three point sealing engagement with the top rail of the sash is thussecured. When the sash is moved down, the edge of the tongue |89 islimited in its movement by the bead |84 which protects the edge andmaintains the tongue under initial tension.

The non-ferrous or non-corrosive header member |80 is preferablyattached to and reinforced by an angle member |90 whichneed not be ofnon-ferrous metal, the members |80 and |90 being secured together in anysuitable manner as by screws or rivets 19|. The member |90 may beprovided with a-flange |92 at its inner edge which will act as a plasterstop and also add strength to the head of the frame. At its outer edge,the vmember |90 is preferably provided with a wide flange |93 whichmaybe secured to thev lintel |94 by screws or mounted in the wall. Thesill of the window is formed of bent or rivets |95 or otherwise extrudedmetal, preferably non-ferrous or non` corrosive metal, and comprises anapron portion 200` which is downwardly flanged at its outer edge at andis then provided with an inward off-set 202 which forms a pocket forcaulking4 203. Back of the apron 200 the sill is formed- .l member 201which preferably terminates in a flange 208 adapted to rest on themasonry. The

member 201 constitutes a supporting leg for the sill. and it may beadjusted to project into the.

hollow flange more or less as the construction of the wall may require.It may be held in adjusted position in the hollow flange 206 in anysuitable manner, as by welding, riveting orthe like. The.

hollow flange 206 is preferably formed to provide an overhanging hookedportion 2|0 which engages and holds the resilient metal sealing memberfor the bottom rail of the sash. Such resilient sealing member comprisesa base 2|| having an off-set portion 2|2 at its upper'` edge adapted tohook under the overhanging hooked portion 2|0 of the hollow flange. bentto form a fold 2|3 engaging the outside of the portion 2| 0, and aresilient tongue 2|4- adapted to engage the inner face of the bottomrail ofthe sash. When the sash is raised` the lower edge of the tongue2|4 engages behind the offset 2|5 of the shouldered seat 294, the edgeof the tongue being thus at all times protected i and the tongue beingheld under initial tension.`

For reinforcing the jamb members of the frame and assisting in securingthe frame in the Wall, a

reinforcing member of the form shown in Fig. 8 may be employed, Thismember comprises a flange 220 adapted to be secured to the jamb channel|50 in any suitable manner, as by being fitted under tongues 22| bentout from the back of the offset portion |53 of the channel member |50.Adjacent to the flange 220 the reinforcing member has a shoulder 225which seats against the end of the olset portion |53. The reinforcingmember has an inclined web 221 which is preferably inclined at aconsiderable angle suchv as approximately 45 to the plane in the back ofthe jamb channel.` The inclined web 221 preferably carries a web thewindow, this web being of any desired width to give the necessarystrength and for engagement with the masonry. The inclined web 221 ispreferablybraced in position by `means of braces 230 formed integralwith or attached to the web 228 and' secured to the flange 5| of thejamb |50, by suitable means such as screws or rivets 232. y v
